PPP Configuration for Dial-Up Connection
The point-to-point protocol is used for dial-up connections.
The gateway can establish either a connection to the Internet
or – if ISDN is used for the connection – to another gateway. If
you use PPP to establish an Internet connection, don’t forget
to configure the firewall accordingly.
The advantages of VoIP over ISDN can be seen especially in
corporate implementation. For example, it is useful when a
very high number of connections occurs between subsidiaries
and one subsidiary does not have a broadband Internet con-
nection. An ISDN B-channel can be connected to the Internet
and up to six voice calls can occur simultaniously over one
ISDN line. All necessary information for setup of the PPP con-
nection is defined in the section [xppp<num>].
The settings are entered as follows:

nection.
